Receiver operating characteristic (ROC) curves for predicting posthepatectomy liver failure

The cut-off value for remnant liver volume (RLV)/body surface area (BSA) was 300 ml/m² (area under the curve (AUC) 0.699, sensitivity 62.5 per cent, specificity 73.2 per cent). The cut-off value for remnant liver proportion was 47.6 per cent (AUC 0.713, sensitivity 52.9 per cent, specificity 84.4 per cent). The cut-off value for standardized functional liver remnant (sFLR) was 42.8 per cent (AUC 0.690, sensitivity 62.6 per cent, specificity 68.8 per cent). The cut-off value for future liver remnant plasma clearance rate of indocyanine green (ICGK-F) was 0.075 (AUC 0.689, sensitivity 52.9 per cent, specificity 90.6 per cent).
